[Mesa-dev] [PATCH] meson: do not search for needless deps

[Erik Faye-Lund]

If we don't want to use these deps, there's no good reason to search
for them in the first place. This should shave a bit of time for the
initial build.

This would be a way of dealing with Gert's suggestion. Goes on top
of the previous patch.

Thoughts?
